S7016 CD/P4ADGC Bearing Product Overview & Core Advantages
The S7016 CD/P4ADGC is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. As a universal matchable (SU) bearing supplied in a pre-matched set, it delivers superior performance in handling combined loads—simultaneously supporting substantial radial loads and bidirectional axial loads. Its P4A tolerance class ensures ultra-precise running accuracy, while the moderate preload (Class C) provides optimal stiffness and rotational precision right from installation. This bearing is engineered for high-speed operation and is characterized by its compact design and exceptional rigidity, making it ideal for demanding industrial environments.
S7016 CD/P4ADGC Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| CD | A 15° contact angle and specific internal design. | Optimized for high-speed performance and axial load capacity. |
| P4A | High precision tolerance class exceeding ABEC 7. | Ensures minimal runout and vibration for ultra-precise applications. |
| DGC | Indicates a sealed bearing with grease lubrication. | Provides contamination protection and long-term, maintenance-free operation. |
S7016 CD/P4ADGC Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact design and moderate preload create a highly rigid bearing unit capable of withstanding significant combined radial and axial loads from both directions.
- Superior High-Speed Performance: The phenolic cage offers low weight and excellent performance at high rotational speeds, contributing to the high limiting speed of 28,000 rpm.
- Precision Engineering: Manufactured to a P4A tolerance class with a consistent 15° contact angle, this bearing guarantees smooth, precise, and quiet operation.
- Long Service Life & Reliability: Constructed from chrome steel rings and balls, and featuring integral seals with pre-applied grease, the bearing is protected from contaminants and is ready for long-lasting, maintenance-free service within a wide temperature range.
